Background

Peripherally Inserted Central Venous Catheters (PICC) are a technique for puncturing a catheter from a vein in a peripheral arm to direct the catheter to the region of the large vein adjacent the heart. In tumor chemotherapy, the PICC technology is used for conveying chemotherapy drugs, so that the direct contact between the chemotherapy drugs and arm veins can be avoided, and the high-speed blood flow of the great veins can be used for quickly flushing and diluting the chemotherapy drugs, so that the stimulation of the drugs to blood vessels is prevented. Can effectively protect the veins of the upper limbs, reduce the occurrence of phlebitis, relieve the pain of patients and improve the life quality of the patients. The PICC-based pipeline needs to be placed in a patient body for one year or even for the whole life, and in order to avoid infection, blood seepage and thrombus blockage, the PICC-based treatment means needs to be disinfected and the sealing adhesive film is replaced at the catheter puncture position frequently, and at least one to two times per week is required on average.
